brilliant explanation really well done.

I’ve watched pretty much all of the quadratic sequence tutorials on RU-vid and yours is by far the most simple one

Thank you very much. Great explanation

you the best

Exam is in a few hours and I just found this

Sir, you have made mistake in first difference that is 11-4 is 7, not 4.

A(n)=n(n+1)=n²+n So A(9)=9²+9=90 Edit:This just takes some basic pattern recognition

I’m confused in the second step how is it 4 isn’t it not 6 this confuses me someone please explain

Thank you so muchhh

Tysm this really helps

This is the base of the worst topic but you made it look so ez

Thank you, Is this higher

Shouldn’t the first number be 7?

This dude just simplified my week long mental crisis-

Thanks u dont know how confusing my teacher made this 1 hour wasted of maths and u have taught me in 30 seconds This is why i hate going to fucking school such a waste of time

First number is 7... because 11-4=7

11-4 is not 5, it must be 7

N×N×N+2

why doesnt it work for 11,18,27,38

But I cannot understand you accent😢

wrong by the looks of it
